Abstract (en)

[origin: US2010061444A1] A method for decoding compressed video information is disclosed. The video information can include a plurality of frames each having a plurality of blocks. The method includes reading from the video information a segment map that associates blocks in the frame with four segment identifiers. Each segment identifier is associated with one or more segment parameters, such as quantization parameters, loop filter type, loop filter strength and sub-pixel interpolation filter. The blocks in each segment are then decoded using the associated segment parameters. Segment parameters can persist to following frames unless overwritten by a subsequent frame. A frame can also include a bit suppressing segmentation, in which case default parameters are sued for all blocks in the frame.
